FlameBlade Posted May 23, 2020 Share Posted May 23, 2020 Server Cluster not working on LAN but is fine on WAN Hello, I am struggling with my server setup. I have two servers which I have in a cluster. This works nicely from outside my LAN. Everything is working as intended from the outside. However, apparently my router does not support NAT Loopback, so I am unable to jump servers when I am on the LAN. So, any ideas on how to fix this? Is it even fixable, or is it just the way, the game works? Which is a bit dumb, I might add ? Link to comment Share on other sites More sharing options...
SylenThunder Posted May 23, 2020 Share Posted May 23, 2020 I have the same issue. Modem used to support NAT Loopback, but an update disabled the feature. The only workaround is to use a VPN that blocks local network traffic. Alternatively, you could use different network hardware that has loopback support.

Regarding the different hardware, I am assuming you mean an extra router and setting up the modem to run in bridge mode? I would very much prefer not having to do this, as a good quality router is fairly expensive. Link to comment Share on other sites More sharing options...

I would very much prefer not having to do this, as a good quality router is fairly expensive. I use PIA for VPN service. They are one of the best out there, and the software allows custom tunneling so I can allow some apps to see my local LAN and block others. Price isn't bad, and it's got a load of features most others don't. (plus no data records if you're into more nefarious activities.) Long-term though hardware is cheaper. I was referencing replacing the modem/router with one that supports loopback, but you could run a bridge too. In my case, the hardware itself supports it, and I only lost the feature because of changes the ISP has been making to the configuration. I have a ticket open to have this feature re-enabled, because by changing my device I will lose some key functions with the ISP's service for the advanced firewall.

FlameBlade Posted May 27, 2020 Author Share Posted May 27, 2020 Hm. I'll look into the VPN thing. Replacing the modem is not an option unfortunately as my ISP has custom firmware on it, so I am pretty convinced that it won't work. Thanks for your input.

iEzJay Posted May 30, 2020 Share Posted May 30, 2020 My router doesn't support NAT Loopback but it's working just fine. What ISP do you have and router? What is your ARK Server setup hosted on? i.e. Dedicated Server? VM? etc? Link to comment Share on other sites More sharing options...
